help on EP Automag using Dye UL PM5 Frame

Hi All,

So I'm trying to build my second EP mag using a Pm5 UL frame and I'm having trouble fitting the RAM in between the frame and rail. There's a 1/4 inch of the ram sticking out so it prevents the rail from sitting there. Has anyone built one of these frames, and how did you make it fit using the stock pm5 board. I could go utb, but I prefer to keep the stock board. As always, any help will be appreciated. The picture below is built by kenjay on mcb.

Ok, here's the picture. As you can see, I'm using an AM rail and the sear is in "firing position", which is the furthest the ram will extend. However, the sear will hit the ram. Unfortunately, the magnet and trigger will prevent me from putting the ram any further down the grip. Any advice? If there's a shorter ram, I'd be truly happy, but I don't think there's anything out there.

I am also unsure if the differences between the UL frame and the stock frame would be an issue. It's very possible that the grip and trigger were re-positioned for that frame. Not to mention it's a UL frame which means a lot of extra space and material have been removed. Anyways, I do see a couple of other issues. It doesn't look like the threads have been machined off of the ram to reduce the overall length. Also, I did have to machine parts of the trigger to make room for the ram as well. I believe this eliminated the spring; the trigger force was dependent on the magnet and microswitch. Obviously the sides of the ram had to be machined/filed down to fit inside the frame AND I believe I had to machine the top side of the ram as well to allow room for the sear. Do you plan on placing a right angled air fitting on the back of the ram? I also had to machine a slot in the side of the trigger frame to route the hose back to the solenoid.

Thanks to Superman. He was able to position the ram vertically where the return magnet used to be. It's pretty tight fit -I'll have to shave the ram quite a bit so I have enough room leftover for the magnet. Looks like I won't need the spacer rail after all. Thanks for all who reviewed my thread. This is why I love AO. I'll update this thread once I'm done.

Can't see how the MPA3 will manage to trip the sear in that position? Looks like the ram piston will be hitting the sear at the wrong angle. The Ultralite frame you're using is smaller than original DM & PM series frames. The Ultralite's a lot narrower at the top of the grip, and that's why it needs different shape grip panels. It's also why you found a lot less room to fit the EP components inside. I've seen at least one other EP mag conversion using an Ultralite frame, and that one used a spacer in between rail and frame.
